sax-1:12am v PATENTEDHAY '1 m4 sum a 0M DEVICE FOR THE LATERALADJUSTMENT AND ADJUSTMENT IN HEIGHT OF THE RAM BEARER ON PRESSES FORNONCUTTING METAL SHAPING BACKGROUND OF THE INVENTION The presentinvention relates to a device for the lateral adjustment and for theadjustment in height of the metals it is of particular importance amongother things and in view of achieving die stampings which are correct asto mass and form,. that the axis of the press die is aligned with theaxis of the die up to a few hundreths of a millimeter. Therefore, it isnecessary that at least one of the presstoolsgenerally speaking thepressdieis adjustable in its position.

Accordin'gto a known adjusting arrangement of this type, the upper partof the ram bearer is guided by a sliding pad lying in an inclined guidepath. This results in an undesirable error as to height in the case ofthe lateral adjustment and in the case of the adjustment as to height itresults in an undesirable lateral deviation, so that the preciseposition of the axis of the ram can be achieved only byway ofa timeconsuming adjusting process. The aligning time of the press tool will beprolonged thereby and the manufacture of the inclined guide paths of theadjusting slits makes machining more expensive. 5

SUMMARY OF THE INVENTION The device constituting the object of thepresent invention' eliminates these disadvantages and permits arelatively quick adjustment of the positionof theram bearer with aprecision which in every case lies within the permissible drop stampingtolerances. This device according 'to the invention is characterized inthat the ram bearer has .a swiveling .peg directed toward the pressslide at a terminal section of the said bearer, the part of theswiveling peg facing "away from the ram bearer projecting into aperpendicular groove of the press slide and being guided in itperpendicularly slidably, and in that a guide-element, which can belifted and lowered by means of an adjusting element and which isslidable in a second perpendicular groove of the press slide, projectsinto the other terminal section of the ram bearer, opposite which oneguide element of the terminal sections of the stamp bearer per force canbe swung to both sides. I

In the case of a special embodiment of this device, the above mentionedswiveling peg is attached to the lower part of the ram bearer and theupper part of the ram' bearer has a slit into which one end of the guideprojects, whereby in the two oppositely located limiting walls of theslit each time an adjusting screw pointing toward the above mentionedend of the guide element is disposed for the purpose of adjusting theupper part of the ram bearer.

Preferably the above mentioned guide slit has a cross sectionpractically of a parallelpiped shape.

In order to avoid completely any error in height occurring duringlateral adjustment, the upper and lower of FIG. 10; and

, 2 I limitingsurface of the guide slit has been curved in such a waythat, upon lateral swinging of the upper part of the ram bearer, ahorizontal shifting of the ram axis results. I

DESCRIPTION OF SPECIFIC EMBODIMENTS More specifically, the exploded viewof a device made in accordance with this invention is shown in FIG. 1with details not necessary for an understanding is equipped with fourattaching bores 3 and is normally rigidly attached to the respectivepress slide 2. Attaching screws6 are'used to connect the bearer l andthe slide 2 between the four attaching bores 3 and correspondingthreaded bores 4. In these embodiments, the bearer! and slide 2 haveparallel faces which are contiguous in the assembled combination.

During operation of the press, the press slide 2 carries out the knownreciprocal movement. That is, the press die (not shownlprotrtidesthrough the bore 5 of the ram bearer 1 and strikes a bottom die (notshown) disposed coaxially to and in the path of movement of the firstpress die. The movement of the press die against the bottom die carriesout the desired noncutting reshaping operation on the pressed part. Thebottom die as well as the driving and guiding elements of the pressslide 2 have not been shown for the sake of clarity since they are notessential to the understanding of the invention.

The ram bearer bores 3 are deliberately kept larger than the diameter ofthe respective pertinent attaching screws 6, (FIG. 2). This sizerelationship between the bores 3 and screws 6 allows for the ram bearerl to be adjusted in its position at any time after the attaching screws6 are released. At the same time, the difference between the diameter ofthe bearer bores 3 and the outside diameter of the attaching screws 6must correspond at least to the maximum range of the desired adjustment.

The ram bearer 1 has a swiveling peg 7 located in its lower portion anddirected toward the press slide 2. In this specific embodiment, the peg7 is forced or slip fit into the corresponding bore 7a disposed in thelower terminal section of the ram bearer 1. When assembled, theswiveling peg 7 projects into bore 8 ofa lower sliding pad 9. The lowersliding pad 9 is guided in a perpendicular groove 10 which is disposedin the lower part of the press slide 2. The width of groove 10corresponds to the width of the sliding pad 9. Thus, the sliding pad 9can execute a movementlimited by the length ofthe groove 10. Themovement of the pad 9 is perpendicular with respect to the axis of peg7. Movement of v the pad 9 occurs when there is relative parallelmovement between bearer l and slide 2 upon the release of screws 6.

The middle portion 1a of the ram bearer l juts outwardly on the frontside thereof. The press die (not shown) projects through the bore 5 thatextends through the middle portion 1a.

The ram bearer head 11 is somewhat narrower and laterally displaced withrespect to the lower body portion of the ram bearer 1. The ram bearerhead 11 constitutes a second terminal section and includes a con- .theram bearer 1 is assembled, the front portion projects into thecontinuous slit l2. Bushing 13 has a continuous axial bore 14. An uppersliding pad 16 includes a peg 15 which engages the axial bore 14. l

The shape and dimension of the upper sliding pad 16 has been so selectedthat the pad 16 will fit into a perpendicular groove 17 located in thepress slide 2. The pad 16 is shiftable in the groove 17 in a directionperpendicular to the axis-of the pad 16. This perpendicularv shifting ofthe upper sliding pad 16 is effected via an adjusting screw 18 thatprojects through bore 19 of the press slide 2. The adjusting screw 18can be screwed into the threaded bore 16a located in the sliding pad 16.The adjusting screw 18 rests with the collar 18a on the upper surface ofthe slide 2.

By a tightening movement of the adjusting screw 18, the sliding pad 16is pulled upwardly along with any parts connected to the pad 16. Areleasing movement of the adjusting screw 18 results in a correspondinglowering movement of the sliding pad 16 and any parts connectedtherewith. The adjusting screw 18 has been secured on the press slideZ'against any axial shifting by means of the covering hood 20. The pad16 along with the ram bearer l and the lower sliding pad 9 move in adirection perpendicular to the axial direction of the swiveling peg 7,bore 5 and peg l5.

Threaded bores 21 and 22 are located in two opposing walls of the rambearer head potion ll. Adjusting screws 23 and 24 can be screwed in thebores 21 and 22, respectively, to place the bushing 13 in the desiredlocation within the continuous slit 12. That is, relative movementbetween the slit 12 and bushing 13 is effected by manipulation of screws23 and 24. The upper sliding pad 16 is shown in its assembled state inFIG. 4 wherein the bushing 13 projects into the ram bearer slit 12. Theram bearer 1 is shiftable with respect to the slide 2 through theoperation of the adjusting screws 23 or 24 with the bushing 13 acting asa support.

The adjusting process of the ram bearer 1 will now be described byreference to FIGS. 1, 5 and 6. First, it is assumed that the position ofthe ram (not shown) requires a lateral correction thereby making itnecessary to shift the ram bearer 1 toward the left (as viewed by theobserver). First, all of the attaching screws 6 as shown in FIG. 2 arereleased so that the ram bearer 1 can be freely shifted within themaximum adjusting range provided by the assembly of this invention. Thenit is simply necessary to release the adjusting screw 24 disposed on theright side of the ram bearer l as shown in FIG. 1. The left handadjusting screw 23 is then screwed inwardly until the axis 25 of the ramhas achieved the desired position. By screwing the adjusting screw 23inwardly, the ram bearer 1 shifts to the left.

The precise movement of the ram bearer 1 occurring during thisadjustment can be seen in FIG. 5. The three characteristic points whichlie in the axis of the slot 12, in the axis 25 of the ram and in theaxis of the swiveling peg 7, as well as in the vertical plane passingthrough the front surface of the head or terminal section 11 of the rambearer 1 are designated in their starting positions by A B and Crespectively, and in their terminal position by A B and C respectively.The points lying in the perpendicular front plane of the press slide 2and corresponding to points A, and C are correspondingly designated by Aand C However, point B; in FIG. 1 has been shown once more on slide 2 toillustrate the movements occurring. The upper sliding pad 13 has beensymbolized by a circle in FIGS. 5 and'6 for the sake of clarity andsimplicity.

There is a basic problem underlying the adjusting process as describedand shown in FIGS. The shifting point B corresponding to the ram axis 25moves horizontally toward the left along a certain path as shown in FIG.5. When the adjusting screw 23 is tightened, the upper ram portion 11 isforced away from the bushing 13. Thus, a swinging movement of the bearer1 is executed around the point C,. At the same time, point Ccorresponding to the axis of the swiveling peg 7 moves slightlydownwardly with the lower sliding pad 9. Slot 12 assumes an obliqueposition and the axis of bushing 13 remains locally fixed with respectto the press slide while the ram would be disposed in the obliqueposition resulting from the movement as described with respect to FIG.5. That is, the ram bearer 1 will move purely in a directionperpendicular to the axis or the ram so that in no case will lateraldeviations occur. By tightening screw 18, relative movement to positionsA B and C is effected as shown in FIG. 6. Therefore, it is possible toachieve a perfect adjustment as to height without being subject to anykind of lateral errors. While there is a slight deviation as to heightwhen a lateral adjustment is made, this slight deviation may becompensated for by a simple adjustment to the height as describedhereinabove. A gradual time consuming adjustment as is necessary inprior art devices to obtain the desired final position of the ram axis25 is no longer required.

In a further embodiment of this invention as shown in FIG. 7, it ispossibleto completely avoid the slight deviation as to height whichoccurs in the lateral adjustment as described hereinabove. The surfaceof the slit 12a is provided with a curvature sothat when bushing 13aglides therealong, the point B representing the axis 25 of the press diewill move on a horizontal line. The specific movement in accordance withthe embodiment of FIG. 7 is shown in FIG. 8. The upper and lowerlimiting surfaces of slit 12a are slightly curved as shown in FIG. 7.When the ram bearer l is shifted so that the slot axis A moves to theleft as shown, the shifting point B moves horizontally toward the left.At the same time, the lower terminal point C of the straight line A -Cmoves upwardly in a movement that is perpendicular to the direction ofthe ram axis 25. The upper terminal point or slot axis A of the straightline A-C describes the desired curve line which is to be made the basisof the form of the slit 120. As in the earlier embodiment describedhereinabove, any vertical adjustment may be made without any lateraldeviation or error. Relative movement effected by screw 18 is shown inFIG. 9.

A third embodiment of the construction made in accordance with thisinvention is shown in FIG. 10. The ram bearer head 11); has a bore 26 inwhich a circularcylindrical bushing 27 can be inserted. Bushing 27 has acontinuous hole 28 having a rectangular cross section. Two threadedbores 29'and 29b are disposed in the ram bearer head 11b and face eachother. Two bores 30 and 30b are located in the walls of the bushing 27and are larger than the outside diameters of the threaded bores 29 and29b, respectively. In the assembled position of bushing 27, threadedbores 29 and 29b align with bores 30 and 30b, respectively, and are heldby two adjusting acrews (not shown) in this mutual position.

A sliding pad 31 has a peg 32 which can be inserted in the continuousbushing hole 28. The height of the 'peg 32 corresponds to that ofbushing hole 28 and is laterally movable therein. The adjusting screws(not shown) fit into the threaded bores 29 and 29b and correspond toscrews 23 and 24 as shown in FIG. 1. Thus,

in the assembled state of the device made in accordance with thisembodiment, the adjusting screws penetrate both threaded bores 29 and2912 as well as the larger bores 30 and 30b. The adjusting screws areseated inside bushing 27 on the rounded flanks of peg 32. The peg 32 hasflattened portions corresponding to the flattened portions of bushing 13in the embodiment shown in FIG. 1.

By releasing the right hand screw and tightening the left hand screw,the ram bearer head 11b is shifted to the left. The resulting turn ofbushing 27 within bore 26 is absorbed by the difference in the diameterof the adjusting screws and the larger bores 30 and 30b. Point A in thiscase moves ona horizontal line as illustrated in FIG. 11. Consequently,point C is lifted slightly and a slight deviation 8 occurs with respectto the height or vertical direction. This vertical deviation, however,also lies within the permissible drop stamping tolerances. Any verticaladjustment as shown in FIG. 12 with this embodiment may again be madewithout any lateral error or deviation. This movement shown in FIG. 12is a complete accord with the embodiments having vertical movement asshown in FIGS. 6 and 9.

A further embodiment of the invention is shown in the use of a singlepart 33 in FIG. 1 instead of the two combined parts 7 and 9. An assemblyequipped with such a simplified part would be perfectly capable offunctioning even though combined parts 7 and 9 were used in the firstspecific embodiment. The use of com bined parts 7 and 9, however, resultin a lower pressure per unit area occurring thereon than in the use ofthe single part 33. I

It is further possible to substitute a single peg 34 which would beperpendicular with respect to the ram bearer l and the slide 2 in placeof the combination of two parts 13 and 16. As shown in FIG. 7, the parts13a and 16a may'be replaced by a single peg 35. In the embodiment asshown in FIG. 10, the sliding pad 31 may be replaced by a square insert36. Basically, it is altogether possible to reverse the arrangementshown in such a way that the swiveling peg 7 would be disposed in theupper portion of the ram bearer l and the adjusting screws 23 and 24 inthe lower part of the ram bearer l.

While the device for the lateral adjustment and adjustment in height ofthe ram bearer on presses for noncutting metal shaping has been shownand described in detail, it is obvious that this invention is not to beconsidered as being limited to the exact form disclosed, and thatchangesin detail and construction may be made therein within the scopeof the invention, without departing from the spirit thereof.
